| Helicobacter pylori infections of the stomach are common worldwide and may cause serious medical problems, ranging from gastritis and its sequelae to gastric carcinoma or lymphoma. Current studies indicate that H. pylori is present in dental plaque, although the number of organisms in individual samples is very low, and these numbers appear to vary from one site to another within the mouth. The presence of this organism in plaque may be intermittent, perhaps occurring as the result of gastroesophageal reflux. It is still unclear if the low numbers of H. pylori present in the mouths of most patients would be sufficient to serve as a source of infection or reinfection for gastric conditions. Whether dental plaque is a significant source for reinfection of the gastric mucosa among patients with fair to poor oral hygiene remains to be confirmed. It has been suggested that attempting to improve oral hygiene through standard periodontal procedures would be prudent as an ancillary measure to conventional ulcer therapy, especially in patients whose gastric infections have proven recalcitrant. H. pylori may also be a cofactor in the recurrence of aphthous ulceration, especially in patients sensitized through gastric colonization and mucosal attachment. |

| Management of tooth avulsion in the permanent dentition often presents a challenge. Definitive treatment planning and consultation with specialists is seldom possible at the time of emergency treatment. Replantation of the avulsed tooth can restore esthetic appearance and occlusal function shortly after the injury. This article describes the management of a child with an avulsed maxillary permanent incisor that had been air-dried for about 18 hours. The replanted incisor retained its esthetic appearance and functionality 2 years after replantation, yet the long-term prognosis is not good because of progressive replacement root resorption. |

| Because of interest in the link between oral and general health, clinicians are increasingly using salivary analyses to diagnose systemic disease and to monitor general health. The reason for this interest lies in the ability of new diagnostic tools, such as sensitive enzyme-linked immunosorbent assays, as well as other technologies, to distinguish a range of salivary components that are biomarkers for changes in the body's health. The noninvasive nature of salivary testing has made it an attractive and effective alternative to blood and urine testing, and home testing kits have made it possible for people to monitor their own health using this diagnostic medium. This paper explores what saliva can reveal about general health, drawing examples from recent research on salivary biomarkers of systemic illness and highlighting the current use, and potential clinical and research applications, of diagnostics based on oral fluids. |

| The results of studies at the University of Toronto now clearly support earlier reports that older adults respond to oral implants in the same manner as younger adults, despite their tendency for systemic illness, including osteoporosis. However, unfavourable jawbone quantity and quality, particularly atrophy of the maxilla, impaired implant success. Furthermore, placement of implants in sites that had been edentulous for shorter periods was associated with greater crestal bone loss, a finding that may have implications for younger adults undergoing such treatment. |

| A series of prospective studies started in the mid-1980s at the University of Toronto have provided evidence of the efficacy and effectiveness of implants in the treatment of the fully and partially edentulous patients. These studies have focused primarily on treatment outcomes at the surgical and prosthodontic levels, with an overall failure rate of 7.7% over a 20-year period. |

| This prospective study is a follow-up to one started at the University of Toronto in 1986. The purpose of this study was to continue longitudinal assessment of implant-supported single-tooth replacements. |

| "Given the research initiatives, it is clear that, as members of Canadian faculties of dentistry, we can and should stop referring to ourselves strictly as 'dental researchers'." |

| There is good evidence to support the claim that periodontitis may be more prevalent among diabetic patients than nondiabetic people. Similarly, studies have shown that periodontal therapy influences glycemic control in people with diabetes mellitus. Given that nearly 10% of Canadians are affected by either type 1 or type 2 diabetes (including those in whom the disease is undiagnosed), all dentists will encounter patients with diabetes. Dental practitioners must be aware of the implications of this relationship and manage their patients' periodontal care accordingly. |
